An object-oriented bridge among architectural styles, aspects and frameworks

We propose an architecture-driven design approach based on the concept of proto-frameworks, aiming to provide an intermediate stage in the transition from architectural models to object-oriented frameworks or applications. The approach is based on an object-oriented materialization of domain-specific architectures derived from domain models, that is the production of concrete computational representations of abstract architectural descriptions using object-oriented technology. A proto-framework materializes, in object-oriented terms, the infrastructure required for cooperation and communication of each architectural component type. In other words, a proto-framework provides the essential abstractions to derive new applications or frameworks by inheritance from the proto-framework classes. In this case, the framework provides very abstract hooks to map specific domain components into a class hierarchy in a white-box fashion. This mapping can produce a specific application, but more important yet, it can produce new domain-specific frameworks that adopt the underlying architectural model. Using an architecture-oriented approach, developers are able to better identify relevant concerns and reason about them at the very conception of the system architecture.Eje: Ingeniería de SoftwareRed de Universidades con Carreras en Informática (RedUNCI

From software architecture descriptions to object-oriented designs

Service-Oriented Architecture (SOA) is becoming a dominant approach for developing distributed enterprise-wide applications. One of the reasons for SOA’s extended use is its capacity to rapidly build applications by assembling alreadyimplemented and Internet-accessible services, which allows software organizations to hasten development of distributed applications and their consequent time-tomarket. However, this approach to develop SOA applications results unsuitable for particular organizations with high-priority and critical demands of internal control, security, flexibility, confidentiality and data integrity of their services, since the development of core functionality may be jeopardized by either uncertainty or changing environment. Although many efforts have focused mainly on facilitating discovering of services, and the outsourcing and reuse of them in SOA-based applications, little attention has been paid to aiding designers in developing services associated with business goals and quality-attribute properties. Moreover, quality-attribute properties of the service assemblies have been disregarded, which often leads to mismatches between the quality-attribute behavior prescribed by the SOA and the one resulting after its implementation.

Supporting Semantically Enhanced Web Service Discovery for Enterprise Application Integration

The availability of sophisticated Web service discovery mechanisms is an essential prerequisite for increasing the levels of efficiency and automation in EAI. In this chapter, we present an approach for developing service registries building on the UDDI standard and offering semantically-enhanced publication and discovery capabilities in order to overcome some of the known limitations of conventional service registries. The approach aspires to promote efficiency in EAI in a number of ways, but primarily by automating the task of evaluating service integrability on the basis of the input and output messages that are defined in the Web service’s interface. The presented solution combines the use of three technology standards to meet its objectives: OWL-DL, for modelling service characteristics and performing fine-grained service matchmaking via DL reasoning, SAWSDL, for creating semantically annotated descriptions of service interfaces, and UDDI, for storing and retrieving syntactic and semantic information about services and service providers

Business Process Management Integration Solution in Financial Sector

It is vital for financial services companies to ensure the rapid implementation of new processes to meet speed-to-market, service quality and compliance requirements. This has to be done against a background of increased complexity. An integrated approach to business processes allows products, processes, systems, data and the applications that underpin them to evolve quickly. Whether it’s providing a loan, setting up an insurance policy, or executing an investment instruction, optimizing the sale-to-fulfillment process will always win new business, cement customer loyalty, and reduce costs. Lack of integration across lending, payments and trading, on the other hand, simply presents competitors who are more efficient with a huge profit opportunity.Web Service, business process, integration, financial services, integration, modeling

Unattended network operations technology assessment study. Technical support for defining advanced satellite systems concepts

The results are summarized of an unattended network operations technology assessment study for the Space Exploration Initiative (SEI). The scope of the work included: (1) identified possible enhancements due to the proposed Mars communications network; (2) identified network operations on Mars; (3) performed a technology assessment of possible supporting technologies based on current and future approaches to network operations; and (4) developed a plan for the testing and development of these technologies. The most important results obtained are as follows: (1) addition of a third Mars Relay Satellite (MRS) and MRS cross link capabilities will enhance the network's fault tolerance capabilities through improved connectivity; (2) network functions can be divided into the six basic ISO network functional groups; (3) distributed artificial intelligence technologies will augment more traditional network management technologies to form the technological infrastructure of a virtually unattended network; and (4) a great effort is required to bring the current network technology levels for manned space communications up to the level needed for an automated fault tolerance Mars communications network
